А то я тоже когда-то искал исходники макро-11, но так и не нашёл.
правов использования кроме как на посмотреть скорее нет
да и не битсэйверс мы которому публиковать такое можно
изкодники большинства утилит (macro-11 link-11 libr-11) тут
http://bitsavers.trailing-edge.com/bits/DEC/pdp11/rsts/RSTS_10.1_src.zip
сам не собирал. нет нужды
